Most homes do well with windows cleaned every four to eight weeks; businesses with customer-facing windows, or homes near busy roads or trees, often benefit from a more frequent round.
Location makes a real difference. Windows near a busy road pick up traffic grime faster; homes surrounded by trees deal with sap, pollen and bird droppings more often; coastal properties get salt residue that builds up faster than inland homes. A shopfront or office relies on clean windows for how the business presents to customers, so a monthly or even fortnightly round is common for commercial premises, while many homes are happy with a round every six to eight weeks.
Frames and sills collect grime just as much as the glass does, and are often skipped by a quick DIY clean — a proper window clean covers both, not just the glass, for a result that actually looks finished rather than clean panes surrounded by grubby frames.
A regular round tends to work out easier than one-off cleans booked irregularly, since windows cleaned to a schedule never get bad enough to need extra work to bring them back up to standard. Properties near busier roads in and around Preston often benefit from a slightly more frequent round than the general guide above.
